Book Description
In a foreword, an author usually elucidates the aim of his book and describes an idealized reader to whom it is addressed. The first task - the formulation of the scope of the book - is the easier one, for the second one involves assessing a reader's personality, and no "specification" should warrant the author's being accused of snobbery, underestimating the reader, or other sins of that kind. It is natural to commence with the first task. The last two decades have been marked by extreme, albeit somewhat unexpected, progress in the unifying approaches to fundamental physical theories. During the same time, a reasonably consistent picture of the early stages in the evolution of the Universe, starting from the time'" 1 s reckoned from the beginning of its inflation, began to take shape. These questions have been separately treated at very different levels; their systematic presentation is the subject of monographs, sometimes very solid ones, containing many formulas not tractable for a layman.

Book Description
Cosmology deals with the current state of thinking about the basic questions at the center of the field of cosmology. More emphasis than usual is put on the connections to related domains of science, such as geometry, relativity, thermodynamics, particle physics, and - in particular - on the intrinsic connections between the different topics. The chapters are illustrated with many figures that are as exact as currently possible, e.g. in the case of geometry and relativity. Readers acquire a graduate-level knowledge of cosmology as it is required to understand the cosmological impact of their particular research topics, as well as an introduction into the current research in the field.

Book Description
This work provides the current theory and observations behind the cosmological phenomenon of dark energy. The approach is comprehensive with rigorous mathematical theory and relevant astronomical observations discussed in context. The book treats the background and history starting with the new-found importance of Einstein’s cosmological constant (proposed long ago) in dark energy formulation, as well as the frontiers of dark energy. The authors do not presuppose advanced knowledge of astronomy, and basic mathematical concepts used in modern cosmology are presented in a simple, but rigorous way. All this makes the book useful for both astronomers and physicists, and also for university students of physical sciences.

Book Description
This book was written in 1944 by Abraham Zelmanov, a prominent scientist working in General relativity and cosmology. Herein he constructs the theory of physical observable quantities in General Relativity (Chronometric Invariants), and applies it to determine all possible cosmological models within the framework of Einsteins theory scenarios of evolution which could be theoretically conceivable for a truly inhomogeneous and anisotropic Universe.

Book Description
The general background of this monograph and the aim of it is described in detail in Chapter I. As stated in 1.7 it is written according to the principle that "when rigour appears to conflict with simplicity, simplicity is given preference", which means that it is intended for a rather broad public. Not only graduate students but also advanced undergraduates should be able to understand at least most of it. This monograph is the result of many years of inspiring discussions with a number of colleagues, for which I want to thank them very much. Especially I should mention the groups in Stockholm and La Jolla: in Stockholm, Dr Carl-Gunne Flilthammar and many of his collaborators, including Drs Lars Block, Per Carlqvist, Lennart lindberg, Michael Raadu, Staffan Torven, Miroslav Babic, and Itlgvar Axniis, and further, Drs Bo Lehnert and Bjorn Bonnevier, all at the Royal Institute of Technology. Of other col leagues in Sweden, I should mention Dr Bertel Laurent, Stockholm University, Dr Aina Elvius, The Stockholm Observatory, and Dr Bengt Hultqvist, Kiruna. In La Jolla my thanks go first of all to Dr Gustaf Arrhenius, who once invited me to La Jolla, which was the start of a most interesting collaboration; further, to Dr W.B.

Book Description
People hunt and kill one another as public entertainment and to win prizes in “Seventh Victim,” the short version of Sheckley’s novel The 10th Victim, which was made into a movie. The twelve other stories in this collection are “The Monsters,” “Cost of Living,” “The Altar,” “Shape,” “The Impacted Man,” “Untouched by Human Hands,” “The King’s Wishes,” “Warm,” “The Demons,” “Specialist,” “Ritual,” and “Beside Still Waters.” From the very beginning of his career, Robert Sheckley was recognized by fans, reviewers, and fellow authors as a master storyteller and the wittiest satirist working in the science fiction field. Open Road is proud to republish his acclaimed body of work, with nearly thirty volumes of full-length fiction and short story collections. Rediscover, or discover for the first time, a master of science fiction who, according to the New York Times, was “a precursor to Douglas Adams.”

Book Description
Dynamics of Stellar Systems focuses on the theoretical problems in stellar dynamics. The book first offers information on stellar dynamics, including historical development, fundamentals of synthetic method, and value of stellar dynamics. The text discusses the fundamental concepts of stellar statistics. Properties of univariate distribution functions; multivariate distribution functions; and statistical properties of stars are explained. The text then describes the elementary theory of galactic rotation and irregular forces in stellar systems. The text also tackles statistical stellar dynamics of neglecting encounters. Considerations include Boltzmann equation in curvilinear coordinates; importance of using one-valued integrals of the motion; and fundamental differential equation of stellar dynamics. The book also underscores the regular orbit of stars and dynamics of centroids. The text describes the dynamics of spherical stellar and rotating stellar systems. The theory of polytropic spheres; basic equations for spherical systems; masses and rotation of galaxies; and boundaries of galaxies are discussed. The text is highly recommended for readers interested in stellar dynamics.

Book Description
Since the first French edition of the book emphasized rather the solid facts of Cosmology than the detailed discussions of controversial results, relatively few revisions were necessary for the English edition. They were made early in 1979 and affected about 5% of the text. The main revisions referred to the distance scale, the dlstribution of galaxies, the X-ray observations of clusters, the cosmic time evolution of quasars and radiogalaxies and the 3 K radiation. A new short bibliography presents the recent articles and the latest proceedings of Symposia; from these the reader can easily trace a more complete list of refer ences. I am happy to thank Professor Beiglbock for suggestions he made to improve Part lIon Spaces of Constant Curvature, and Drs. S. and J. Mitton for translating the manuscript into English. I also thank with pleasure Marie-Ange Sevin for correcting the final version. J. Heidmann March 1980, Meudon, France Preface The aim of this book is to present the fundamentals of cosmology. Its subject is the study of the universe on a grand scale: - on a grand distance scale, since from the start, we shall be escaping the con fines of our own Galaxy to explore space as far as the limits of the observable universe, some ten thousand million light years away; - and on a grand time scale, as we shall look back into the past to the very first moments of the initial expansion, about twelve thousand million years ago.
